Proxmax VE 8 当前版本升级，如果是要跨版本需要用别的姿势。
一、升级前检查
pveversion -v uname -a df -h
二、禁用Enterprise 源
nano /etc/apt/sources.list.d/pve-enterprise.list
注释：
#deb https://enterprise.proxmox.com/debian/pve bookworm pve-enterprise
三、禁用CEPH Enterprise 源
nano /etc/apt/sources.list.d/ceph.list[/shell] 注释： [code]# deb https://enterprise.proxmox.com/debian/ceph-quincy bookworm enterprise
四、设置免费源
nano /etc/apt/sources.list
添加
deb http://ftp.hk.debian.org/debian bookworm main contrib deb http://ftp.hk.debian.org/debian bookworm-updates main contrib deb http://security.debian.org bookworm-security main contrib deb http://download.proxmox.com/debian/pve bookworm pve-no-subscription
和设置CEPH免费源
echo "deb http://download.proxmox.com/debian/ceph-quincy bookworm no-subscription" \ > /etc/apt/sources.list.d/ceph.list
四、尝试更新
apt update
确认不报错并执行
apt dist-upgrade
